JSB 25.4's lubed?

I just got my order of JSB 25.4's and when I started loading mags for a chrony test on my Widlcat it seemed that the pellets were lubed. Has JSB started lubing their 25.4's like they lube the
34 grain mk2's? I did seem to have gained 10 fps from the last shot string taken a week ago. Both strings were from the same starting fill pressure and shot under the same conditions (indoors).
